Reduced thickness tracking device

ABSTRACT

In a tracking device, a crescent-shaped PCB partially encircles a battery to minimize thickness of the device. A speaker and an LED emit alerts upon command of a control apparatus or in response to motion or temperature sensed by sensor. A local network has one hub to tracking devices and a wider area network has multiple hubs for more detailed tracking of devices. A wide area network tracks devices anywhere and stores data of each tracking device including its last known position and its sensor data.

This application is a continuation of U.S. application Ser. No.14/301213, filed Jun. 10, 2014, the disclosure of which is herebyexpressly incorporated by reference herein in its entirety.

This application is related to U.S. patent application Ser. No.14/301236, filed Jun. 10, 2014; and U.S. patent application Ser. No.14/301250, filed Jun. 10, 2014.

BACKGROUND

This invention is in the field of wireless electronic tracking devicesand networks.

There are numerous devices and systems for tracking objects, pets andindividuals. For example, radio frequency identification (RFID) tagshave long been used to track objects, pets, cattle, and hospitalpatients. A reader generates an electromagnetic field in the tag andthat field powers a small transmitter in the tag that emits a signalwith the identity of the tag. The reader picks up the tag's radio wavesand interprets the frequencies as meaningful data. RFID tags requireclose proximity between the reader and the tag and such systems areoften limited to generating only identity information and do not provideinformation about the motion, heading, time, temperature or otherenvironmental characteristics in the vicinity of the tag.

There are systems with sensors attached to clothing or objects formonitoring the physical activity of those wearing the clothing of themotion of the object. See, for example, Pub. No. US 2013/0274587. It hassensor and transmitter to send information about the motion of theobject and the temperature sensed by the object. A base station uses GPSor triangulation to identify the location of the object. Although themonitoring system may have one or more alerts, no alerts are provided onthe sensors on the clothing of the users.

Other tracking systems use tracking sensors with built-in GPS systemsand transceivers for establishing wireless communication with a network.One such system is found in U.S. Pat. No. 8,665,784. However, the powerrequired to operate a GPS system often rapidly drains the battery ofsuch tracking sensors or requires the sensors to have a relatively largepackage, which is not readily attached to small objects, pets or people.

The prior art solutions do not address the problem of finding small,lost objects in within a room or house as well as at a distance. Knownsolutions are not compatible or cost effective for individuals. Largesensors that require recharging many batteries impose too high a levelof maintenance on an individual. None of the above solutions will find asmall sensor that may be hidden in drawer or under a pillow. They do notprovide control apparatus for commanding the sensor to emit an audibleor visual alert. The prior art shown above is silent regarding theproblems of pairing sensors with location, remote controlling a sensor,and using a sensor to remote control a sensor control device.

SUMMARY

This summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription. This summary is not intended to identify key features ofthe claimed subject matter, nor is it intended to be used as an aid indetermining the scope of the claimed subject matter.

Embodiments of the tracking device of the invention are configurable byan individual user to help find lost objects and monitor pets and theactivities of small children or hospital patients. The tracking deviceis a comprehensive solution to locate, monitor and track missing pets,people, luggage, inventory, tools and items of interest. In someembodiments the tracking device incorporates various sensors and controlmechanisms that make the tracking device a versatile multi-functiondevice which can remotely control other devices such as smartphones,tablets, or computers. The device is instrumental in shaping andcreating a market for the “internet of things” by allowing a user ornetwork of users to seamlessly share sensor data while providing aregional or global picture of environmental conditions such astemperature, movement, trends in a particular area or simply acollaborative picture of all dogs active in a particular city at aspecific time. The tracking device has a speaker and a light emittingdiode. A control apparatus is associated with the tracking device. Thecontrol apparatus may command the tracking device to emit an alert,including a buzz or flashing light. If a tracked object is inside adrawer or under a pillow, the person searching for the object will hearthe buzz or see the flashing light. The control apparatus may also setits own alerts to trigger based upon the distance between the trackingdevice and the control apparatus. Alerts can be based upon pairing thelocation of the tracking device to the alert so that alerts are onlyprovided at predetermined locales and/or predetermined times.

Embodiments of the tracking device conserve power and space. Theelectronics of the tracking device are carried on a crescent-shapedprinted circuit board that partially encircles a battery. Encircling thebattery with the printed circuit board reduces the thickness of thetracking device. Top and bottom covers enclose the printed circuit boardand the battery. One cover has an opening to access the battery. In someembodiments the battery may be wirelessly recharged with inductive orsolar powered chargers.

The electronics include a Bluetooth low energy transmitter that hasenough computing power to control sensors and the tracking device. Aceramic antenna further conserves space. In some embodiments the sensorsinclude a multi-axis sensor such as a nine-axis motion sensor, and atemperature sensor. Embodiments may omit GPS sensing circuitry and relyon the GPS circuitry in control devices. Other embodiments include GPScircuitry. Using one or more programs in a control apparatus, a trackingdevice can be set to trigger one or more alerts depending upon thedistance between the tracking device and the control apparatus.

There are multiple network embodiments for the tracking devices. In alocal network a hub communicates with local tracking devices and relaystheir sensor outputs to a cloud/internet site. Multiple hubs can form awider area network that allows the hubs to communicate with each otherand triangulate the approximate position of each tracking device. In astill wider area network, tracking devices anywhere in the world can bemonitored by position, time of day, motion and any other characteristicor parameter sensed by the a tracking device.

The tracking devices are assigned to an owner-user who may grantprivileges to others for using the devices of the owner. The owner-usermay also have shared privileges with tracking devices of other users.Objects lost anywhere in the world may be located by using position dataprovided by other control devices that carry the control program and areregistered to the cloud/internet site.

The embodiments described herein provide a computer program that isinstalled on a control apparatus. The computer program enables thecontrol apparatus to detect tracking devices within range of the controlapparatus and acquire control of the tracking device unless anothercontrol apparatus already controls the device. The control apparatus mayalso release from its control one or more selected tracking devices. Thecontrol program also allows the user to keep private the information ofthe tracking device. Once set to private, only the control apparatus orother designated apparatuses or individuals will have access to datafrom the tracking device.

The control program allows the user of the user to select at least onealert. The control device or the tracking device or both may generatethe alerts. In order to trigger the alert, the tracking devicebroadcasts a beacon signal via a Bluetooth transceiver. The signalstrength of the beacon signal received by the control apparatus isrepresentative of the distance or range between the control apparatusand the tacking apparatus. The signal strength is considered a conditionfor a distance alert. If a control apparatus suddenly receives a beaconsignal of a controlled tracking device, the control apparatus mayindicate the device has returned to a location proximate the controlapparatus. Likewise, failure to detect a beacon signal of a controlledtracking device indicates the device is outside the range of the controlapparatus. The relative strength of the beacon signal is proportional tothe proximity between the control apparatus and the controlled trackingdevice.

The control apparatus or the tracking device or both may monitor otherconditions. Each other condition and combinations of two or moreconditions may be paired or otherwise associated with each other toprovide multiple conditions for triggering an alert. In addition to therange signal beacon, the tracking device may carry one or more sensorsand each sensor may output one or more signals representative of otherconditions monitored by the sensors. Other conditions include and arenot limited to motion of the sensor in any direction or in a particulardirection; temperature and other signals representative of time, thegeographic location of the tracking device or both, motion and otherphysical, biological or chemical conditions being monitored by sensors.As such, each condition monitored may be associated or paired with anyother one or more conditions to provide multiple conditions that must bemet to trigger an alert.

The beacon signal includes the identification information for thetracking device and a signal representative of the status of the chargeof the battery. The program displays both the range and battery statusinformation. As explained above, the location of the tracking device maybe detected by other control devices, which may assist the owner inlocating a lost tracking device. Accordingly, the control apparatus, ifassociated with network of other control apparatuses, may acquireinformation about the location of a tracking device remote from theother networked control apparatus. The control program provides afeature for selecting a map displaying the remote location of eachtracking device controlled by the control apparatus.

In other embodiments the control program allows the control system toremotely control operation of the tracking device or allow the trackingdevice to remotely control the control apparatus or both. The controlprogram enables the control apparatus to activate an audible or visualalarm or both by selecting a corresponding alarm button shown on adisplay of the control program. The control program allows the controlapparatus to allow one of more of its operations to be controlled by thetracking device. The control program permits the user to set themulti-function button on the tracking device to operate a camera, anemail or a text messaging system of the control apparatus. In addition,the multi-function button may be programmed with the control program toactivate an audible alarm on the control apparatus. For example,pressing the multi-function button may cause a smartphone controlapparatus to emit a distinctive sound.

DETAILED DESCRIPTION

While exemplary embodiments have been illustrated and described, it willbe appreciated that various changes can be made therein withoutdeparting from the spirit and scope of the invention.

One embodiment of a tracking device 10 is shown in FIGS. 1A, 1B. Thetracking device 10 is an assembly having outside covers 11, 16. Thecovers are made of glass filled acrylonitrile butadiene styrene (ABS)thermoplastic which is light in weight, can be injection molded and isresistant to impact, heat, water, acids, alkalis, alcohols and oils. Thecovers 11, 16 have circular-shaped bodies 3 a, 3 b, each with an annularwall 4 a, 4 b. The covers also form a through-hole 17 for receiving acord or chain to attach the tracking device to an object, a pet or theclothing of a person.

Turning to FIGS. 1C, 1D, the covers 11, 16 enclose a printed circuitboard (PCB) 12 and a battery 15. The PCB 12 has a crescent-shaped bodywith an outer edge 2 a having a radius of curvature slightly smallerthan the radius of curvature of the covers 11, 16 and an inner edge 2 bwith a smaller radius of curvature. Two circular arcs of differentdiameters thus define the crescent shape of the PCB 12. The PCB 12 hasan opening 13 a for receiving a circular battery 15.

The diameter of the battery 15 is smaller than the diameter of opening13 in the PCB 12. The battery 15 has one terminal on its surface andanother terminal on its edge.

The edge of the battery engages a conductive edge connector 18 on theinner edge 2 b of the PCB 12. Another conductor has a spring-biased body19 that extends from the PCB 12 toward the middle of a surface of thebattery 15. The battery 15 is held in the opening 13 between the twocovers 11, 16 and against the conductive edge connector 18 on the inneredge 2 b of the PCB 12. Cover 11 has a ripple wave design on itssurface.

Cover 16 has an opening 13 b sufficient to receive the battery 15. Athreaded battery cover 8 a, a matching threaded annular wall 8 b and anO-ring 7 secures battery 15 in the openings 13 a, 13 b. A detent 9 inthe surface of the battery cover 8 receives an opening tool, such ascrewdriver or the edge of a coin (not shown). Inserting the tool in thedetent and rotating the cover 8 a open the cover to access the battery.In an alternate embodiment as shown in FIG. 1E, the slot 9 is replacedby two spaced-apart holes 110, 111. A key 115 has two prongs 112, 113that fit into the spaced-apart holes and allow a user to apply torque tothe cover 8 a to open it and remove the battery 15.

The tracking device is assembled by inserting a PCB 12 with componentcircuitry on the inside surface of cover 16. The other cover 11 isplaced on top of cover 16 to define a cavity that holds the battery 15and the PCB 12. The two covers are ultrasonically sealed to resist wateror other materials from entering the device 10. A battery is insertedthrough opening 13 b in cover 16 and the batter cover 8 a engages theO-ring 7 and the threaded wall 8 b. Cover 8 a rotates in oppositedirections to close or open. By encircling the battery with the PCB 12,the PCB does not increase the thickness of the assembly that isdetermined only by the covers 11, 16 and the thickness of the battery16. Some embodiments are 5 mm thin and 40 mm in diameter. Unlike otherdevices that use batteries, the PCB does not contribute to the thicknessof the device 10 because the battery 15 does not rest on the PCB 12 butis partially encircled by the opening 13 c in the PCB 12.

A multi-function button 14 a extends from an opening defined byhalf-oval walls 14 b, 14 c in the sidewall of the junction of theannular walls 4 a, and 4 b. In one embodiment there is a singlemulti-function rubber button 14 a that extends from the edge of thedevice. Button 14 a is held in place by wall edges 14 b, 14 c thatoverlap surface 14 d to hold the rubber button 14 a inside the covers11,16. The rubber button is aligned with a mechanical button 14 e thatis attached to the PCB 12 and coupled to core device 21. The covers 11,16 and the PCB 12 have aligned openings 17 a, 17 b, 17 c that create anexternal key ring hole 17 for holding a key ring, a carrying chain orcord. As will be explained below, the component circuitry has a speakerfor sounding one or more alarms. The edge of the covers defines a keyring hole 17 that has on or more small holes that may be sealed. Inthose embodiments a removable rubber plug 5 is inserted into the hole toprevent moisture and water from entering the cavity holding thecomponent circuitry 20. As an alternative, a larger rubber plug couldfill the entire keyhole opening 17 or at least cover the annular innersurface of the keyhole.

FIG. 2 shows the component circuitry 20 of the PCB 12, including aBluetooth low energy (BTLE) core device 21. The core device 21 includesa transceiver for sending and receiving information signals and controlsignals. The core device also includes a microprocessor, read onlymemory and random access memory sufficient to enable the core device 21control the other components on the PCB 12. In a further embodiment, apermanent or removable memory device is added to the device. The memorymay be added through another side hole similar to the side hole formedby walls 14 b, 14 c that hold the rubber button 14 d in place. Thememory device could be inserted or removed through the second sidewallhole and a rubber stopper, similar to rubber button 14 a, would seal theopening second sidewall hole. The memory device may hold informationsensed by the sensors.

The core device 21 is assigned a unique identification code known to theuser and the core device broadcasts the code at periodic intervals. Themaximum range of the core device 21 is approximately 300 feet.Broadcasts are made using a ceramic antenna 22. The ceramic antennasaves space. A typical ceramic antenna may take up only 20% of the spaceoccupied by a trace antenna, thereby contributing to the overall smallsize of tracking device 10.

The core device 21 controls a speaker 23 and a light emitting diode(LED) 24. The speaker 23 and the LED 24 provide alarms for the trackingdevice 10. The cover 11 is thin enough to allow light to pass through.In alternate embodiments and clear or highly translucent window isprovided in the cover 11 above the LED 24.

The core device 21 is connected to one or more sensors 25, 26 or anynumber of sensors 27. The sensors in some embodiments sense physicalparameters experienced by the tracking device 20, including and notlimited to displacement, motion, acceleration, electromagneticradiation, radioactivity, temperature, sound, pressure and otherphysical parameters. In some embodiments, a sensor 25 is a combined9-axis motion sensor and temperature sensor. The sensor 25 has anaccelerometer, gyroscope, and magnetometer for each axis. Theinformation output by the 9-axis sensor enables the receiver to trackthe position of the tracking device from one location to anotherlocation. The motion of the tracking device can be monitoredcontinuously as long as a receiver is close enough to record the motionoutput information of the 9-axis sensor 25. As an alternative, theinformation may be stored in the memory.

A multi-function button 14 a is operable to perform one of morefunctions described in more detail below. The single button 14 a on thetracking device 10 and one or more control programs resident on acontrol apparatus 37 (see FIG. 3) operate together to set one or morealarms, pair triggers and remotely control operations of the controlapparatus 37. Those skilled in the art understand that a controlapparatus may be any electronic device with processor, memory andcommunication ability including and not limited to a smartphone, adesktop computer, a laptop or notebook computer, a tablet computer, apersonal digital assistant, or any equivalent device that can store andhold programs and data, execute programs, receive and/or transmitinformation and commands via wired or wireless channels ofcommunication.

Some embodiments of the invention are equipped with rechargeablebatteries that may be recharged via a wireless or wired rechargingapparatus or a solar recharging apparatus. Wireless chargers, also knownas induction chargers, typically place one coil in a charging device orpad that is connected to an AC power source and another (receiver) coilinside the device with a rechargeable battery. As shown in FIG. 2, atransmitter module 28 a has a transmitter coil 28 b that produces atime-varying electro-magnetic field that is coupled to a receiver coil29 b of a receiver module 29 a on the PCB 12. The receiver module 29 aalso includes circuitry to convert AC voltage and current to DC voltageand current. The core device 21 controls operations of the receivermodule 29 a and turns it on and off to recharge the battery 15 asneeded. Transmitter and receiver modules are available from a number ofintegrated device manufacturers.

Other embodiments of the invention may have wired rechargers. These arewell known devices and may be incorporated into tracking devices 10 byproviding a suitable port (not shown) to receive power from an externalpower source. However, such external ports provide openings in thecovers 11, 16 where water or other fluids may gain entry to the cavityholding the PCB 12 and its component circuitry 20.

Still other embodiments may have solar recharging systems such as shownin FIG. 2B. One such solar recharging system 120 has one or more solarcells 125, 126 located on respective covers 11, 16 and connected to abattery regulator circuit 128 and rechargeable battery 115. Core device21 is connected to the regulator circuit 128 and battery 115. The coredevice 21 uses the solar current to know whether the tracking device isin available light or not. In that way, the solar cells provide a dualrole by acting as light sensors. This allows further flexibility bypairing any other sensed parameter to the presence or absence of light.The amount of current generated by the solar cells 125, 126 indicatesthe intensity of light received by the tracking device 10.

Other embodiments of the tracking device have circuitry for harvestingRF power to charge the battery 115. Athttp://www.hindawi.com/journals/apec/2010/591640/there is described anRF harvester having a GMS antenna, one or more resonant circuits,boosters, peak detectors and an adder. The circuitry contains passivecomponents and is designed to have tuned circuits at known frequenciesof cell phone towers (960 MHz) and Bluetooth devices (2.4 GHz). Theboosters are Villard voltage multipliers. Reported test results show theRF harvester located within 500 meters of a cell tower was capable ofgenerating 158 nW and successfully operated a calculator and a lightemitting diode.

Turning to FIG. 3, an embodiment of a first system 30 is shown. Thesystem includes tracking devices TD1 32, TD2 32, . . . TDN 33. Eachtracking device 10 is paired with a control apparatus 37 which may be acomputer, a tablet or a smartphone. The control apparatus 37 has atransceiver for establishing a wireless connection to the cloud/internet35. In this patent a symbolic cloud and the reference number 35 aremetaphors for the internet itself, for local area networks, for widearea networks and for individual sites on the internet where users maystore and retrieve programs and data. Control apparatus 37 may createone or more alerts based upon the relative location between the controlapparatus 37 and tracking devices 31-33 and information detected by thesensors 27 in the devices. The system 30 may be used to find a lostobject attached to a tracking device 10, set an alert for when anobject, pet or person bearing a tracking device 10 moves into or out ofone or more predetermined ranges, and pair alerts with locations ormotions of the tracking device 10. The owner-user may share with othersinformation transmitted by the tracking devices 31-33 and control ofdevices 31-33.

Accordingly, another user with a control apparatus 38 may use the sametracking devices 31-33 to establish alerts on the control apparatus 38that are different from those of the alerts created by control apparatus37.

Remote controls for television sets are frequently lost. The system 30solves the problem of finding a lost remote control or other object 34.A tracking device 31 is attached to a remote control or object 34. Anysuitable means for attaching is acceptable including hook-and-loopfasteners or adhesives that attach to the object 34 and the trackingdevice 31. Other attachment means include a chain or cord for attachingthe object 34 via a key ring hole. The control apparatus 37 has aprogram 100 that provides a control menu associated with the trackingdevice 31. The tracking device 31 has a speaker 23 and an LED 24 thatoperate upon commands received from the control apparatus 37. Thecontrol apparatus 37 sends a suitable signal to the core device 21 tocause the speaker 23 to generate a distinctive sound, such as a buzz orring, and to operate the LED 24 in a flashing mode, or both, in order tolocate the object 34.

The system 30 may also monitor when an object, pet or person enters orleaves a predetermined range with respect to the control apparatus 37.For example, another tracking device 32 has a cord or chain 36connecting via a key ring hole to and object, a collar of a pet, to anarticle of a person's clothing, surrounding a wrist of a small child oran Alzheimer patient. The control apparatus 37 sets one or more alertsdepending upon the distance between the control apparatus 37 and thetracking device 32. If a parent were shopping with a small child, theparent may program the control apparatus 37 to issue one or more alertsdepending upon the distance between the child wearing tracking device 32and parent carrying the control apparatus 37. If the child and parentbecame separated by a first predetermined distance, such as 10-15 feet,the control apparatus would emit a first alert, such as one of the manysounds or vibration patterns that are included on a smartphone. If theseparation becomes larger, such as 30-50 feet, a second alert wouldoccur with a different sound and/or vibration. A third alert could beprovided when the tracking device 32 lost radio contact with the controlapparatus 37.

The system 30 may remind a user to take along key personal items beforeleaving a predetermined location. Tracking devices 33 could be attachedto a key ring, a laptop or tablet computer, a brief case, a purse, awallet, luggage, a backpack or other personal items. A user may carrythe tracked items during travel from one place to another. If the userdeparts a location and forgets the tracked item, an alert would sound onthe control apparatus 37 to advise the user he or she forgot the trackeditem. Such alerts may be paired to specific locations to that they areonly triggered when and where the user wants.

The core device 21 of each tracking device 31 has a clock. The beaconsignal and any signal from a sensor may include the time the signal issent. The clock also may be used to extend the life of the battery 15.The control apparatus 37 may set the tracking device to a power savingsmode where its broadcast signal is only active for a short period oftime compared to the intervals between activation. The core device alsotracks time and any alert may be paired to one or more chosen times orday, week, month or year.

The system 30 may also alert user when an item has returned. Forexample, assume the tracking device 32 is attached to an automobileoperated by another member of the user's household. When the driver ofthat automobile returns home, the tracking device will trigger an alertin the control apparatus 37 to alert the user that the automobilebearing the tracking device 32 has returned within range of the controlapparatus 37.

The tracking devices 33 may have their alerts paired to one or morelocations. For example, if a user places tracking device 32 on a briefcase or backpack, the user has little need to be warned of leaving thevicinity of the briefcase or backpack when the user is at home or atwork. Those locations may be excluded from alerts and all otherlocations could be active. This embodiment would be especially forcommuters who take a train or bus. The alarm could sound if the commutermoves more than 10 feet from the tracking device on the briefcase orbackpack.

Among the numerous options available to the user is the option to haveone or more alerts activated on the control device 37, the trackingdevice 32 or both. Recall that some embodiments include a 9-axis motionand temperature sensor 25. Sensor readings are transmitted by coredevice 21 and received and recorded by the control apparatuses 37, 38and any other control apparatus with permission to control the trackingdevice 31. So long as the tracking device 31 is within range of at leastone control apparatus, the GPS location of the apparatus and the motionof the tracking device 31 can be viewed on line in real time or at alater time by other users, such as 38. In one embodiment a trackingdevice 31 is fixed to a snowboard and the snowboarder carries a controlapparatus 37 that continuously receives the motion data from trackingdevice 31.

All travel of the snowboard, including vertical travel up ramps andacrobatic flips and turns of the snowboarder will be sensed by the9-axis sensor and sent to the first control apparatus 37. That apparatuscan be set to record the information received from the tracking device31 or to continuously transmit the information to the cloud/internet 35.

Another feature of each tracking device is the ability of the owner ofthe device to share device information or control or both with others.For example, a remote user with control apparatus 38 and with sharedprivileges may access the cloud/internet 35 and use the recorded motioninformation to drive a display showing an icon moving in accordance withthe same motion as the tracking device 31. In some embodiments theshared users are designated as “friends” of one or more tracking devicesthat are generally under the control of the owner of the trackingdevice. As will be explained later, an owner may voluntarily transfercontrol of a tracking device to another authorized user or simplyrelinquish control of a tracking device to any other authorized user whois or passes within range of the relinquished tracking device. Anauthorized user is, at a minimum, a user who has a control apparatuswith a copy of an operating program for controlling tracking devices. Inother embodiments authorized users are registered with a central usersite that may be accessed through the interne.

Embodiments with the 9-axis temperature sensor may be used to pairlocation, time, temperature, direction, and position, velocity andacceleration in each of three axes of motion. For example, a user couldset an alert to show whether the speed of a tracking device 31 exceededa threshold of 10 miles per hour in the time between 10 AM to 11 AM onAug. 4, 2014, when the temperature was between 75-85° F. while travelingnorth) (0-90°) within the city limits of Seattle, Wash. As such, motion,time, temperature heading and location may all be paired together or inany combination of one or more types of sensed information to set analert. The pairing of tracking device 31 with a smartphone having GPShas endless possibilities. Motion data can be configured to user-definedalerts that include activating the speaker and LED 24. For instance, ifa user was jogging and his speed dropped below a threshold, the speaker23 on the tracking device 10 would buzz. In another embodiment thetracking device 10 monitors temperature outdoors, and buzz from speaker23 could warn the user when the temperature dropped below a level thatwould harm outdoor plants. In some embodiments the 9-axis sensor enablesthe system 30 to control functions of the control apparatus 37. Acontrol program 100 installed on the control apparatus 37 records motionof the tracking device 31 and associates the recoded motion with afunction of the control apparatus 37. With the control program 100 open,control apparatus 37 records a motion or set of motions of the trackingdevice 32. The user then associates the recorded motion of set ofmotions with a function provided on the control apparatus. Suchfunctions include triggering an alert on the control apparatus 37 whenthe tracking device 32 moves in any direction, taking a picture with thecontrol apparatus 37 in response to a first predetermined motion orfirst combination of motions of the tracking device 32, placing a phonecall from the control apparatus (smartphone) 37 in response to anothermotion or another combination of motions of the tracking device 32,sending an email or text message from the control apparatus 37 inresponse to a third motion or third combination of motions of thetracking device 32. For example, the sensor 25 could be attached to adoor or a window and any movement of the door or window would set off anaudible or visual alarm on the control apparatus 37. A combination ofmotions such as shaking the tracking device 32 up and down could commandthe control apparatus 37 to take a picture. Moving the tracking device32 left and right could command the control device 37 to send a message(email or text) to one or more addressees with a predeterminedannouncement, such as, a reminder to take medication. A user may map outspecific locations, click the button and the tracking device 32 willsave the place of interest. For example, a surveyor could walk aspecific path, and mark specific points of interest such as corners of aroad, or edges of a hill. The geographic properties of each point ofinterest would be saved and mapped out. Thus, the tracking device 10 hasuses in the fields of gardening, home security, child monitoring,health/fitness, sports applications, navigation, commercial andindustrial monitoring and safety appliances.

Turning to FIG. 4, a first network 40 has tracking devices TD1-TDN,31-33 that are in wireless communication with a hub 41. The hub 41 maybe connected to a gateway system 47 that in turn is connected to thecloud/internet 35. In some embodiments of the first network 40, the hub41 is directly connected to communicate with the cloud/internet 35. Thehub 41 listens for signals from the tracking devices 31-33. The hub hasBluetooth or other wireless communication apparatus and can sense therange of each tracking device within its effective field. Upon receivingsignals from one or more tracking devices, the hub relays informationassociated with the tracking devices to the cloud/internet site 35.Likewise, the hub 41 may send control information received from thecloud/internet site 35 to each or all the tracking devices 31-33.

Each tracking device 31-33 and the cloud/internet 35 associated with thedevices has an owner and may have one or more shared users. As used inthis patent, the term “owner” applies to a user of a tracking device 10who has primary control over the tracking device 10 and thecloud/internet 35 associated with the tracking device. The embodimentenvisions local, regional, national and international networks withinthe scope of cloud/internet 35. It also envisions registered owner-usersof tracking devices and others register users with one or more dedicatedcloud/internet sites 35 for collecting information about trackingdevices 10. An owner-user may grant one or more privileges to others,known as “friends”, allowing the other users some or all access orcontrol of the owner's tracking devices and owner's account on thecloud/internet site 35. For example, one owner-user may give a friend aprivilege to view all data on the cloud/internet site 35 or view dataonly associated with one or more tracking devices chosen by theowner-user for sharing. Even when the owner permits other users to seethe data, some data may be marked “private” and excluded from the viewof the shared user. An owner may also permit other users to control one,more, or all functions of individual tracking devices of the owner. Anowner may also allow device data to be posted publicly, so that any usercan view the data.

The friend feature solves a potential problem of locating lost trackingdevices. If a friend finds a lost item of owner, the friend maydiscretely notify the owner that the friend has found the lost trackingdevice (and the object attached to the device) by calling the owner orsending the owner an email or text message that the friend found thetracking device at a particular location and time. The email couldinclude a map with a pin showing the location.

In an alternative friend-based scenario, assume a user of controlapparatus 72 who was granted privileges for the lost device 32 by itsowner detects the lost device. The owner sees on the database that theuser of control apparatus 72 is close to the lost device 32 and also hasprivileges for the lost device 32. The owner may contact the user ofcontrol apparatus 72 via telephone or email and ask the user to find thelost device 32 by initiating a sound or light alert on the device 32.

Shared use has a number of advantages. For example, assume the owner ofthe device 31 is away from home and receives a call from a member of hisfamily asking for help finding a lost remote control attached totracking device 31. The owner could log into the cloud/internet and senda suitable command to the tracking device 31 to operate its speaker 23and its LED 24. If the owner had shared control of the tracking devicewith other family members, then the shared user could send the commandto generate an alarm without contacting the owner.

The embodiment of first network 40 helps integrated multiple trackingdevices 31-33 and Bluetooth devices. A control apparatus 37 (e.g.smartphone) does not have to control the tracking devices. Instead, alltracking devices 10 for an owner are registered in the hub 41 where eachcan be securely accessed from a smartphone or other control apparatusanywhere in the world. The registered tracking devices can be used forhome security, automation, or playing games with friends across theworld.

A second, wider area network embodiment 45 is shown in FIG. 5. There aplurality of hubs H11, H12, H21, . . . H1N, HMN are distributed over apredetermined area, such as a warehouse, college campus, hospital,airports, and offices. In a warehouse, tracking devices 33 are attachedto stored items and any particular stored item can be immediatelylocated by triangulating its position from the range signals detected bythe hubs. On a college campus, the tracking devices could locate a lostsmartphone, computer or book. In hospitals and offices the trackingdevices could be attached to files so that anyone could find a desiredfile by accessing the cloud/internet 35.

A third network embodiment 50 is shown in FIG. 6. An owner of multipletracking devices 31, 32, 33 operates a control apparatus 70 that hastwo-way communication via cloud/internet 35 with the tracking devices31, 32, 33. A server 58 is also in two-way communication with thecloud/internet 35. The server 58 includes one or more databases 60 thatkeep records on owners, users and each tracking device. For user of thenetwork 50, the database 60 would show the devices owned by the user orthose devices for which the user had granted or received one or moreprivileges or are marked for public access, the identity of each devicethat is owned or subject to a privilege granted or received, theinformation reported by each sensor of each device, including and notlimited to the time the information was received and the location of thecontrol apparatus that receives the information. At any time the owner70 of the tracking devices 31-33 may view the historic information onthe location and sensors of each tracking device of the owner, includingthe last known location of the tracking device and when the last knownlocation was recorded in the database 60.

The owner's control apparatus 70 may be beyond the range of thetransceivers in core devices 21 of the tracking devices. A number ofother control devices 71-74 may be within range of one or more of thetransceivers 21 in the tracking devices. Each tracking device uses itscore device transceiver 21 to broadcast a periodic beacon signal withinformation including the identity of the tracking device andinformation from the sensors 25-27 of the respective tracking devices.Each control apparatus 71-74 receives the beacon broadcast and relaysthe information in the broadcast to the cloud/internet 35, including theGPS location of the control apparatus. The control apparatuses 71-74 donot need permission from the owner of the tracking devices to receiveand forward the identity and sensor information. As long as the controlprogram 100 for tracking devices is running, each control apparatus willreceive the beacon signal from the tracking devices. No permission isrequired to receive the beacon signal. The retransmission of beaconinformation by the control apparatuses 71-74 imposes no hardship on thembecause each one likely transmits its own beacon signal to a cellularphone network or a local or wide area network.

The third network embodiment 50 may be used to locate misplaced itemsthat are beyond the range of a control apparatus. An owner may accessthe database 60 and mark one or more of the owned devices as “lost.”Assume that device 32 is owned by the operator of control apparatus 70and is attached to a tablet computer (not shown). Assume another usercarries control apparatus 73 and has no shared privileges for trackingdevice 32. Nevertheless, when control apparatus 73 passes within rangeof the beacon signal from tracking device 32, the identity of the lostdevice 32 and its approximate GPS location will be relayed via controlapparatus 73 to the cloud/internet 35 and recorded on the database 60.That allows the owner to know the general location of the lost device32. The approximate location can be displayed on a suitable applicationsuch as Google Maps, or MapQuest to provide the owner with local streetsor landmarks where he may physically search for the lost device.

The database has numerous uses. Tracking devices 33 may be distributedover a large geographic area where each tracking device is incommunication with a hub, such as shown in FIG. 5. The tracking devicesmay be located at one or more known locations or the hubs may provideGPS data. The sensors on the tracking devices could report theirtemperatures, air pressure, humidity, and other environmentalcharacteristics via the hubs to provide data for a database 60 of thevariable environmental characteristics of the geographic area.

There is a virtually unlimited number of sensors that can be used toprovide trigger signals and a similar unlimited of responses or alertsthat may be given in response to the trigger signals. Each trackingdevice has a button 14 a and may have one or more sensors 25-27. Thebutton and each sensor may generate a trigger signal. Trigger signalsmay be combined in any number of combinations and/or sequences oftrigger signals to generate particular trigger signals depending uponthe occurrence of predetermined combinations and/or sequences of triggersignals. The tracking devices and control apparatuses may also generateone or more responses or alerts upon receipt of trigger signals andcombinations thereof.

Button 14 a may be pressed one or more times to generate one or morebutton trigger signals. Two or more sequential pressings of the button14 a are an alternate trigger signal. The button may be held down togenerate a long duration trigger signal or promptly released to generatea short trigger signal. A combination of long and short duration signalsmay also be used as a trigger signal.

For embodiments having a 9-axis sensor, any motion or combination and/orsequence of specific types of motion may be used to generate triggersignals. For example, when a tracking device 31 is used to secure a dooror a window, any motion of the sensor may be a trigger signal. In otherembodiments, specific user-defined spatial displacements are receivedand stored in the control apparatus as trigger signals for a response.For example, moving a tracking device left to right, shaking thetracking device up and down, moving the tracking device to define aletters, such as the letter “L”, or moving the tracking device to definea shape such as a circle or square, are but a few custom motions. Theshapes and letters could be paired with a click of the button 14 a toindicate the start of a motion and second click when the custom motionis completed. The control apparatus would remember the click to startand stop and the motion between clicks.

Range is another trigger for the tracking devices. On the controlapparatus the user may define one or more ranges for generatingresponses including alerts. One potential use is keeping a parentadvised of the relative location of a child while shopping in a store.Different responses or alerts could be given at different ranges as thedistance between the child and the parent varies. In the hive system ofFIGS. 4 and 5, a trigger may be given when a tracking device leaves orenters the hive.

Location is a still another trigger. In some embodiments, the trackingdevice may carry its own GPS device and broadcast its latitude andlongitude coordinates. In other embodiments, the tracking device mayrely upon the GPS coordinates of any control apparatus that participatesin systems such as shown in FIGS. 4-6 and is within range of anytracking device. In still other embodiments, the location of one controlapparatus 37 may be paired with the range of one tracking device. Forexample, in the basic system shown in FIG. 4 control apparatus 37provides the location of the control apparatus using its GPS functionand pairs that location with the range between the control apparatus 37and the tracking device 31. A user can have an alert triggered when thedistance between the control apparatus 37 and the tracking device 31exceeds a predetermined distance selected by the operator of the controlapparatus 37. A user can also set an alert that is only active at a“home” location to remind the user to take a laptop to which thetracking device 31 is fixed when the user leaves home. However, if thelocation were different from the “home” location, no alert would begiven.

Time is another trigger signal. As explained above, time of day may becombined with other trigger signals to enable or disable one or morealerts, such as enabling a motion alert during the night but disablingthe alert during the day.

Other trigger signals and their combinations and/or sequences arepossible with added sensors. The tracking devices of the embodiments ofthe invention may use any of a vast number of sensors including and notlimited to sensors for motion. Distance, velocity and acceleration,temperature, pressure, magnetic fields, gravity, humidity, moisture,vibration, pressure, light, electrical fields, ionizing and non-ionizingradiation, cosmic rays, and other physical aspects of the externalenvironment; analytes for chemical or biological substances includingand not limited to sensors for detecting toxic compositions such ascarbon monoxide, carbon dioxide, methane, and other hazardous orpoisonous components. The tracking devices may be worn as badges bypersonnel to detect ambient analytes and physical parameters. The datacollected by the tracking device may be sent to the data collectioncenter 58 where others can analyze it and provide responses or alerts tothe personnel wearing the tracking devices.

The control apparatus has a program that allows the user to createcustom trigger signals including combinations and/or sequences ofindividual trigger signals. The control apparatus, the tracking deviceor both may generate one or more responses to a trigger signals or acombination of trigger signals. The tracking device, the controlapparatus or both may give responses or alerts.

The foregoing embodiments of tracking devices provide audible and visualalerts, but could also vibrate the tracking device upon receipt of acommand or trigger signal. In the embodiments described above thetracking devices and the control apparatus may establish a remotecontrol system between themselves to cause one of the system componentsto execute a function upon receipt of a predetermined command or triggersignal from the other component. For example, a custom motion triggersignal of the tracking device may remotely control the control apparatusto take a picture, send a message via email of SMS, make a phone call toa predetermined party, and combinations thereof such as take and send apicture to a predetermined party or group of predetermined recipients.
